BASIC COMPONENTS OF ENVIRONMENTAL HEALTH

THE FIVE BASIC COMPONENTS OF ENVIRONMENTAL HEALTH.

Each of these components gives in different pieces of information to describe various problems in Environmental health and then give out their solutions too.

The following are the Five basic components of Environmental Health:

1. Toxicology

It is a discipline of environmental health which deals with the study of how environmental exposures lead different health outcomes. It is considered as an essential component. The research is done on animals so, as to understand the possible health outcomes in humans too.

Toxicology has the advantage of doing different random, controlled experiments as they use animals as their subjects. But, yes animals and our body are different biologically so, there are chances that the results which come on animals may not be the same for humans.

2. Environmental Epidemiology

It is the study of the relationship between human health and environmental exposures like exposure to radiations, chemicals, etc. It is also an observational study which observes the vulnerabilities that people have already experienced.

They can’t knowingly put humans to exposure to such harmful things as it might be hazardous and can cause diseases. So, the experiments are kept observational.

As they can’t use live subjects so, they believe in observing the results which are already present. They want to study the effects on humans so, they don’t use animals as their subjects.

3. Exposure science

It is that discipline, which studies human exposure to environmental contaminants. It is done by both identifying the exposure and also checking it’s quantity.

Exposure science can also be used to support environmental epidemiology. It describes in brief, the environmental exposures that lead to a specific health outcome and also helps in identifying common vulnerabilities whose health results may be better understood through a toxicology study.

It can also be used in risk assessment to identify whether the current level of exposure, exceeds the recommended level or not? Exposure science has a plus point as it can accurately find out the quantity of exposures to specific chemicals. But, a drawback is that it can’t generate any information about health outcomes like the other disciplines.

4. Environmental Law

It is the law which includes the statues, network of treaties, customary and common laws and regulations regarding the effects of human activity on the natural environment. This law is made to protect our environment from the harmful external damage.

5. Environmental Engineering

It is the study of scientific and engineering principles for the protection of human populations from the adverse factors. It includes improvement of environmental quality and also the protection of our environment form dangerous effects natural and human activities.

"Environmental health" &
"Environmental protection".

These terms are very much similar to each other.

Both, Environmental health and Environmental protection are very much similar. “Environmental health” focuses on the built and natural environments for the wellness of human health. Whereas, “Environmental protection” is concerned towards saving or protecting our natural environment for the wellbeing of human health and our ecosystem.

Research in this field limits the harmful exposures with the help of natural things like soil, air food, water, etc.
